Laser 101

Back in the '90s, blasting wrinkles meant horror-flick-like oozing and months of redness as "ablative" lasers burned off the skin's surface and a younger-looking version grew in.

Not so with the new generation of smarter lasers, which target the hallmarks of aging—creases, brown spots, broken capillaries, sagginess—without destroying the skin you've got. The result? Faster healing, so you can get back in makeup and return to work with smoother skin in as little as 24 hours. Still, any searing laser beam has the potential to scar or damage pigment (especially for women of color), so treatments are best left to an M.D., who can adjust the intensity to work with your skin tone. And sun-worshippers beware: Because many lasers target pigment, give the beach a four- to six-week break before your first session. Here, a laser-by-laser guide to the treatments that'll suit your trouble spots, budget, and schedule.

THE TREATMENT: Nonablative (i.e., surface skin is left intact) Fractional Resurfacing

What It's For: Smoothing fine-to-moderate lines, evening out brown spots, and improving overall glow with quick weekend recovery. (It's often referred to as "Fraxel," the brand that debuted the device in 2004.)

How It Works: Heat generated by the laser penetrates deep into the skin and stimulates collagen production without annihilating your epidermis (translation: no oozing or rawness). It's typically performed over a course of three to five 25-minute treatments, one to two months apart, under topical anesthesia. And it's safer for ethnic skin types than ablative lasers, but even women as light in tone as Lucy Liu should proceed with extra caution (your doctor can calibrate the laser at a lower intensity to minimize risks, but you may need extra sessions).

How It Feels: Less painful than ablative procedures, these treatments give the sensation of heat rather than pins and needles. Feels like a bad sunburn for about 10 minutes post-procedure; afterward, skin is pink and sandpapery for three to five days but can be camouflaged with concealer.

Price: $600 to $1200 per treatment

THE TREATMENT: Ablative (i.e., skin-wounding) Fractional Resurfacing

What It's For: Smoothing fine-to-deep lines and evening out brown spots in a single treatment. Can also help tighten lax skin and carpet bomb broken capillaries if they fall in the laser's direct path.

How It Works: The laser beam strikes the skin in thousands of places, destroying tissue a millimeter deep in those microscopic spots only (think perforated paper). Surrounding skin remains intact, allowing for faster recovery than the original ablative devices but more intense results than the nonablative fractional laser. The hole-punching fires up the body's wound-healing response, which generates collagen and smooths wrinkles. It's ablative and therefore riskier for women of color, but can be executed successfully at a doctor's discretion.

How It Feels: Generally performed with local anesthesia similar to what you'd get in a dentist's office. After 15 minutes of post-treatment discomfort and an application of ice packs, pain is minimal. For 24 to 36 hours, skin oozes and bleeds (just as pretty as it sounds), followed by five days of crustiness. Once crust peels, new, pink skin emerges and makeup can be worn; complete healing within two weeks. (FYI, this laser comes in three varieties: CO2, Erbium, and YSGG. CO2 is harshest, while YSGG offers the quickest, easiest recovery.)

Price: $1500 to $5000
